Privacy
The short version: what you type stays in your browser.
What you type
Every calculation happens in your browser. Prices, yields, dates and amounts you enter are never sent to Coupon Beacon or anyone else, and the downloaded CSV schedule is made on your device. Apart from loading the site's own files, the pages make no network requests; the one exception is the page-view count described below.
What is stored on your device
One thing: if you pick Light or Dark with the theme button, that choice is saved in your browser's local storage under the key couponbeacon-theme, so the next page opens the same way. Setting the button back to Auto deletes it, and so does clearing this site's data in your browser settings. Your calculator inputs are not saved.
Cookies, accounts and ads
There are none. There is no sign-up, no advertising and no tracking across other sites.
Page-view counts
The site uses Cloudflare Web Analytics, which our host Cloudflare adds to each page, to count page views. It does not use cookies or track you across sites, and it never receives what you type into the calculators.
Links to other sites
Pages link to sources such as the eCFR, TreasuryDirect, the MSRB and Investor.gov, to sister sites and to two recommended services, CleanTempMail and WebTraceCheck. Those sites have their own privacy policies, which apply once you follow a link.
